Chocolate Or Mud Why Not Both

My railing boots are pretty dirty once again and I use my dirty boots to crush some chocolate for this slave. He has to slurp everything under my boot feet. Is this brown stain mud? Or is it chocolate?! Thats what he has to find out with his tongue! :-D The juices filling makes the whole mess sticky and the slave struggles to get it off - but he has no chance - hell eat whatever I make him eat!
